1 Claim. (01. 158-406) My invention relates to an improvement in gas burners, and has for its object to provide a gas burner having a high efficiency. Another object is to provide a gas burner composed of a number of small units between which air may pass to cool the burner units and then aid in the support of combustion of the gas. Another object is to provide a gas burner as above described, in which the individual units may be readily removed for repair or replacement. Another object is to provide a gas burner as above described, the units of which are supported on a frame which carries a gas manifold provided with openings or jets to supply gas to the several gas burner units. A still further object is to provide a gas burner as above described, the units of which provide for the intake of gas and ample air and a diverted travel of the gas and air through the burner unit for the thorough mixing of the gas and air preparatory for a complete combustion. These and other objects will be more fully explained as this description progresses.

Now referring to the drawing; Fig. 1 is a perspective view of a gas burner which is an assembly of my gas burner units. Fig. 2 is a plan view of a portion of a gas burner composed of my gas burner units as seen from the line IIII in Fig. 3. Fig. 3 is a side and sectional view of Fig. 2 as seen from the line IIIIII in Fig. 2. Fig. 4 is a plan view of the bottom end of one of the gas burner units. Fig. 5 is a bottom view of the inner box-like element of the gas burner unit.

In the drawing is shown a gas burner composed of a series of gas burner units A. The units are composed of an outer box like element 10 which is open at the top and is provided with an integral bottom 11 with a Venturi tube 12 integral with the bottom 11 and positioned on the center axis of the box like element 10. At 13 is a second box like element which is open at the bottom and closed at the top. The box like element 13 is small enough in diameter that it will go inside the box like element 10 and over the Venturi tube 12, so the wall of the box-like element will set approximately midway between the Venturi tube and the wall of the box-like element 10. Portions of the lower end of the box-like element 13 are cut away as shown at 14 to provide openings through which gas and air may pass, as will be later explained, and also to provide legs 15 which rest on the bottom 11 and support the boxlike element 13. Around the top of the box-like element 13 is a flange 16 which is smaller in diameter than the inside diameter of the box-like element 10. At intervals around the flange 16 are outwardly projecting portions 17 which are adapted to contact or fit inside the top edge of the wall of the box-like element 10 so that when the boxlike element 13 is placed within the box-like element 10 the flange 16 will be spaced away from the wall of the box-like element 10 and leave a narrow crack or opening 13 through which the mixture of gas and air flows to the point of combustion.

The portions 17 are wide enough that when the burner is in operation a break in the flame will occur at the places where the portions 17 are and this affords an opportunity for air, which is a secondary air supply, to pass to the inside of the flame and support a more complete combustion of the gas and air mixture being emitted from the openings 18.

At 19 is a frame or supporting element for the gas burner units A. The frame 19 is supported at either end on any suitable supporting element 76 such as a steel I beam or channel 20 or concrete or masonry as shown at 21.

At 22 are shown gas manifolds which are shown as a part of the frame 19 although they may be separate from the frame if desired. At 23 is so shown an L shaped seat to receive and hold gas burner units A and hold them in position to form the composite gas burner. In the gas manifolds are holes or gas jets 24 which are positioned on the center axis of the Venturi tube 12 when the 5 gas burner unit is placed in position on the supporting frame 19 as shown in Figs. 2 and 3.

While the box-like elements 10 and 13 are shown to be round in form, it will be understood that they may be made in other shapes such as 91 elliptical, square, rectangular, hexagonal or any other polygonal form and still retain the principle and intention of my improved gas burnerand gas burner unit.

The operation of my improved gas burner and 95 gas burner unit is as follows: Gas is turned into the gas manifolds 22 from where it is jetted through the gas jets 24 into the Venturi tube 12.

Air enters the tube at the bottom and the gas and air together flow upwardly through the Venturi tube and are discharged into the box-like element 13 whereupon the mixture is forced to flow downward around the Venturi tube and inside the box-like element 13 to the bottom of the box-like element 13 where it passes through the cut away portion or openings 14 into the boxlike element 10 where the. gas and air mixture is forced to flow upwardly and is emitted out of the box-like element 10 through the cracks or openings 18. Due to heat set up above the burner from the combustion taking place there, air naturally flows upwardly around the outside of the gas burner units A and mixes as a secondary air supply with the gas and air mixture coming from the gas burner units A and at a point just above the gas burner units combustion of the gas and air mixture takes place.

Simultaneously with the occurrence of combus-' tion just described, part of the air coming up around the outside of the burner units passes through holes or interruptions in the flame caused by the portions 17, as above described, to the inside of the flame and acts as a secondary air to support a more complete combustion of the gas and air mixture coming from the openings 18 of the gas burner units. During the course of travel of the gas and air through the gas burner unit the gas and air become thoroughly mixed, due to the irregular line of travel they are forced to take.

Such modifications of my invention may be employed as lie within the scope of the appended claim without departing from the spirit and in tention of my invention. Now having fully described my invention, what I claim as new and desire to secure by Letters Patent is;

In a gas burner, said gas burner being composed of a series of gas burner units, a frame for the support of said gas burner units, said gas burner units being loosely set on said frame, gas manifolds carried by said frame and means in said manifolds for supplying gas to each of said gas burner units, each of said gas burner units comprising a pair of cylindrical box-like elements, one of said cylindrical box-like elements being open at the top and closed at the bottom, a tubular element integral with said bottom and passing therethrough, a second box-like element positioned within the first said box-like element and over said tubular element, said second boxlike element being closed at the top and open at the bottom and having openings in the bottom portion of the wall thereof, an outwardly extending flange around the upper edge of said second box-like element and outwardly projecting portions on said flange which fit between the walls of the first said box-like element to form a uniform opening around the top of said gas burner unit through which gaseous fuel may be emitted, all substantially as shown and described.
